E March 25, 2016 Followup from the Pelican Staff: Locate the check valve on the cylinder head, follow the large black plastic hose from the secondary air pump to the valve. Enter the 5 character trouble codes in the search box and submit the search. I will check lines and pump operation. The secondary air system is used to improve catalytic converter efficiency and reduce the emission of harmful combustion byproducts in the automotive exhaust. .
What is it called so I can order it? The enables both circuits simultaneously when Air system operations id desired. June 12, 2017 Followup from the Pelican Staff: That is a normal configuration. Other related secondary air injection codes are P0410, P0411, P0413, P0414, P0415, P0416, P0417, P0418, P0419, P041F, P044F, P0491, and P0492. The stored code or codes will be read, and then cleared. I hooked the valve and pump back up and cleared the codes. November 13, 2017 Followup from the Pelican Staff: We don't currently have that tech article. Any other ideas would be great in case that was not the issue.
I also replaced the check valve, secondary fuse and relay and still no luck. Unless you can confirm the part has been superseded, then there would be information on what to with the vacuum line from the control solenoid.

The secondary air pump should be mounted securely to the vehicle. Problems with it should not cause drivability issues. If present and the pump doesn't run, replace the pump.
Could it be an electrical issue somewhere? The cause of the above check engine codes are the pump that distributes debris downstream into the valves. September 23, 2017 Followup from the Pelican Staff: I'd need the fault descriptions. If there is vacuum, replace the solenoid. August 1, 2015 Followup from the Pelican Staff: If you are referring to the curved lip, it should face the engine. Once you do that, run the pump, can you see the change in precat o2 sensors? March 21, 2015 Followup from the Pelican Staff: The pump only runs when cold and not for very long.

Seems important to get this right since it's a part of the exhaust system connecting to the cylinder head. I am not missing the hose if there is no valve for it to even attach to ya know. It will have the procedure, special tools and torque specs. I went ahead and bought a used secondary air pump but the codes are still there. Thanks for the great write up and all the expert advice. The valve in this model has no vacuum line and takes valve 11727553066.
